LPC

LPmud is a very fascinating game to play, but even more so to develop.
There's very little that you can't do if you really set your mind to it,
though it might be a bit tricky at times. The strongest lure naturally is
the multi-user quality of the game; to actually have hundreds, yes even
thousands of players enjoying your code is a great feeling.

This tutorial will teach you the necessary basic knowledge needed to
create code in the LPmud environment, and Genesis in particular. It's
no easy read though, so please expect to spend a few days assimilating
and learning what I'll try to teach you here. Apart from this dire
warning I would just like to wish you a pleasurable time coding once the
initial hurdle is behind you.
